He's a celebrity fitness trainer to Kate Upton, and Jennifer Lopez wrote the foreword to his new book, "Ultimate Family Wellness: The No-Excuses Program For Diet, Fitness and Lifelong Health."
And David Kirsch is also a single parent of twin 6 1/2-year-old girls.
His book doesn't just speak to stressed-out, super-busy single parents juggling family and career but to all of the multi-hyphenate, time-stretched among us who swear there aren't enough hours, minutes or even seconds in the day to workout.
The book includes Kirsch's 5-5-5-plan, which includes five quick exercises (many for just adults), that he says can help you lose as many as five pounds in five days when also combined with family-friendly recipes that take less than 15 minutes to prepare. There's also guidance about exercising with your kids, fueling motivation and behavior modification.

Perhaps surprisingly, Kirsch said that having twin girls has made him less hardcore when it comes to always having to eat perfectly. He doesn't use the words "diet" and "fat" around his daughters but instead makes them aware of better nutrition and fitness choices. "We live in a society where healthy choices aren't usually the most popular choices," says Kirsch, adding it's important to make family fitness and nutrition "fun, fresh, inspiring and engaging."
Here are seven family-friendly tips from Kirsch:

- There's no greater way to teach kids than by example, Kirsch said. Teach your children to love and respect and take care of the bodies they were born with.
